Definitions
- an intersection P of a line tangent to an intersection S of a straight line Q in a tire axial direction passing through a midpoint of the tire cross-sectional height SHo and a tire outer wall and an tire external diameter line Z is positioned more to a tire equatorial plane side than a region R that corresponds to 90% of a rim width HRW of the standard rim having the tire equatorial plane as a center.
- an angle formed by the tire outer wall in an upper region of the side wall portion is set so as to be gradual in the tire axial direction.
- a demarcation face between the inner side rubber 11 a and the outer side rubber 11 b is preferably formed as a face inclining from the outer side in the tire radial direction toward the inner side in the tire radial direction from the tire outer side toward the tire inner side; and this inclined face is preferably positioned in the tire outer side so as to be more to the outer side in the tire radial direction than in the tire inner side.
